PIPE-HANGER.

Application tiled November 3, 1910. Serial No. 590,456.

To all whom it may concer-n: y

Be it ltnown that I, GEORGE I. Rocitwoon, a citizen of the United States, residing at lVorcester, in Athe 4county of lVorcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Pipe-Hangers, of which the following is a specilication,. accompanied by drawings' forming a part of the same.

My invention relates to improvements in a support fora pipe hanger which is designed to afford `means for supporting the pipe hanger from a horizontal surface, and it consists in an improved method of construction of said support by which it is held more securely in position, as hereinafter described and pointed out in the annexed claim.

Figure 1 is a' perspective view of 4the support forvmy pipe hanger. Fi 2 is a perspectlive view of the support rom the side opposite to that shown in Fig. 1. Fig. 3 is a side view of the support shown in central vertical section. Fig. 4 shows a pipe hanger in position supporting a pipe Wit-h the support shown in end view.

Similar reference characters refer to similar parts in the different figures.

Referring to the accompanying drawings; as shownl in Fig. 4 the pipe 1 is supported by the ring 2 which is provided with a hub 3 into which the screw threaded'end 4 of a rod 5 is inserted and held therein by a check nut 6. The vupper end 7. of the rod 5 is susf pended from a horizontal surface 8 by a support 9, the construction of which is shown in Figs. 1, .2 and 3. The support 9 is provided witha hub 10 which is arranged to extend downwardly when a rim 11 is in position to contact with the horizontal surface 8. 'The upper end 7 of the rodis provided with screw threads .and is inserted through the hub 10. A nut is then attached to the screw threaded end of the rod and is arranged to fit a rectangular space 12 in the interior of the support 9, thereby vpreventing the rotation of the rod separately from the support 9. The support 9 is constructed of sheet met-al, or other elastic material, with the opening 12 and hub 10 in approximately the center and surrounded by the rim 11 which is designed'to be in contact .with the horizontal surface 8. The body of the support 9 is arranged to extend on two sides .of the opening 12, which are 'each provided with a'n upwardly proj'ecting boss 13 surrounding a screw hole 14. As shown in Fig. 3 the bosses 13 do not normally extend as far upwardlyx asthe/rim 11, and the elasticity of the support is relied on to eX- ert a downward pressure upon the screws inserted in the openings .14 whenl the bosses 13 are drawn, by rotation of the screws, into contact with the horizont-al surface 8. This downward pressure upon the screwsprevents their accidental displacement and holds them securely in position to supporty the hanger. i,...

To aid in fixing. the support 9 in position upon the horizontal surface 8, notches 15 are provided in-the rirn 11 o`n opposite sides' of the support 9, by means `ofiwhichg the support 9 may beadjustd relatively to a mark'fupon the surface 8; As the hangers are ordinarily used` in series this enables an entire series to be placed to correspond with a` single line. The rim 11 of the support 9 is also provided upon opposite sides of a line lconnecting the notches 15 with upwardly projecting spurs 16, which are caused to enter the surface 8 by pressure upon the support 9 after the notches 15 are correctly placed, thereby preventing fur-l ther rotation or., movement of the support 9 upon the surface 8 and securely holdin it in position until the screws are inserted.

By the insertion of the screws in the Surface 8 the projecting extremities of the bosses 13 are drawn'into contact with the surface 8, and the elasticity ofthe material .forming the support 9 exerts a downward pressure upon the screws in the surface 8, thereby securing them in position as has already been pointed out.

VI claim,

A pipe hanger, comprising a support 1 adapted to be attached to and depend from a horizontal surface, said support rbeing struck from a single piece ofelastic sheet metal and consisting of an elongated plate entirely surrounded by a raised rim and provided atits center with a hub inclosing a rect-angular space and depending from .said hub a cylindrical tn bul'ai` Section, said plate having a vscrew h'ole between said hub and the ends pf said pla-te and midway l e tween the rim on opposite Sides Vof the plate, whereby the strain exert-ed bythe attaching screwupon the yielding horizontal plate I 4will be eq-ully vresisted by the tlm n opposite sides of the plate.A
